SPECIFICATION forming part of Letters Patent N o. 730,443, dated June 9,1903.

Application led October 30, 1902. Serial No. 129,340. (No model.)

To @ZZ whom, t may oon/ecrit:

Be it known that I, EDMUND H. DUCHEMIN, of Newark,county of Essex, Stateof New Jersey, have invented an Improvement in Curtains, of which thefollowing description= in connection with the accompanying drawings, isa specificatiomlike characters on the drawings representing like parts.

This invention relates to curtains especially adapted for use on cars,and has for its object to construct an improved form of locking deviceadapted to hold the curtain in any position that it may be set and whenoperated to release the curtain to enable it to he drawn up by theactionof the spring, yet the cnrtain is at all times free to be drawn down,and my improved locking device has an operating device which projectsfrom the casing at any -desirable elevation adapted to be Operated bypressure, like the pressure upon a button, and when operated to releasethe curtain.

Figure l shows in front elevation a curtain embodying this invention.Fig. 2 is an enlarged detail showing my improved locking device in sideelevation. Fig. 3 is an enlarged detail showing the lockingL device Vinfront elevation. Fight is a section takeny on the dotted line at 4, Fig.l. Fig. 5 is an end view of the spring-roller, showing the means forholding thespring wound up.

@represents a curtain which is supported upon a spring-rollerof theHartshorn or other type, and a a2 are the end journals of said roller. Atoothed wheel a3 is secured to one of the end journals, as a2, forinstance, and said wheel is normally engaged by a pawl a4, which may beheld pressed into engagement with said wheel by a spring a5 or bygravity. A pawl-litting lever a is provided, pivoted at a7, which isadapted to engage the pawl 61,4 and when operated to lift said pawl outof engagement with the toothed wheel. The pawllifting lever is made as abell-crank lever. The pawl-lifting lever is acted upon by a springawhich engages one arm of said lever. A link a9 is connected to theother arm of said lever, which extends down along the casing Within arecess al, formed or provided therein, and the lower end of said linkai' is connected to one arm of a bell-crank lever cl2,

Vcurtain is removed from its bearings, I have provided one of the endjournals, as of', with a hole through it, through which a pin b may bedriven, which engages a iiange b on the end of the roller, and whenthejournals of 'the roller are placed in their bearings, and

thereby prevented from operating, the pin b will be removed. In order tohold the spring while it is being wound up, the end journal a will beprovided with a single notch h2. A

-pawl b3, which is connected to the roller, is

adapted to entersaid notch, and thereby lock the journal. When, however,the curtain is placed in its bearings, the journal a will be placed withthe notch in its under side, and the pawl will at such time fall bygravity out of engagement with the journal.

Having thus described thy-invention, what I claim as new, and desire tosecure by Letters Patent, is

A curtain having a spring-roller,a case having a vertical recess in oneof its side portions, provided with an opening at its lower end, atoothed wheel secured to one of the end journals of said roller, a pawlengaging said toothed wheel, a pivoted spring-controlled pawl-liftinglever, and means for operating said lever consisting of a link connectedto said lever which passes down through said vertical recess, a pivotedbell-cranklever connected to the lower end of said link having a buttonattached to one of its arms which projects through the opening at thelower end of the casing, substantially as described.

In testimony whereof I have signed my name to this specication in thepresence of vtwo subscribing witnesses.
